This makes it easier to re-generate the test diffs. The build system
will properly set DI_EDID_DECODE/DI_EDID_PRINT (and will rebuild
these tools if they are out-of-date).

The three character PNP ID is a key to manufacturer name database. It
may be desirable to report the manufacturer's real name than just PNP ID
which can be misleading, e.g. MSI refers to Microstep and not MSI GmbH.
This builds the PNP ID database into libdisplay-info to avoid having to
find and parse files at runtime.
tool/gen-search-table.py started as a copy of Wayland 1.21.0's
src/embed.py and took influence from
10945c4ed8/conv.py
However, our script parses the text file shipped in hwdata package in
Debian (and presumably other distributions) rather than the original
CSV.

I believe this is what we intended, and it is what I want.
It could lead to duplicating low-level API in high-level API at first,
but once we start seeing DisplayID in the wild, the high-level functions
need to start looking into both EDID and DisplayID APIs to deliver the
desired information.

I was scratching my head for a good while, why does the test suite fail
straight out of upstream on one EDID file. Turns out I was using a
different version of edid-decode than CI, which caused the recorded diff
patch to fail to apply. I was missing
41507c0b5f "ci: update edid-decode"
Make an explicit note about this dependency.

Add two small shell utilities to generate and compare diffs between
edid-decode and di-edid-decode. Store the diffs in-tree and add tests
to ensure they don't regress. Run the tests in CI with a pinned
installation of edid-decode.
One EDID blob is added to the test collection: dell-2408wfp-dp. It's
extracted [1] from the edid-decode repository.
